EPUB3 file sends Readium into infinite loop, but works fine on VitalSource

I have a file (with a bunch of demos for interactive JavaScript elements for a textbook) that passes EPUB3 validation and works fine on the VitalSource EPUB3 reader for both Mac and WIndows, but it throws Readium into an infinite loop.

Looking at http://idpf.org/forum/topic-1499, it seems as if someone is willing to look at instances of troublesome EPUB3 files. If that's still the case, where could I send mine?
